OVEN FOR BAKING, ROASTING, 650C.A

SPECIFICATION forming' part of Letters Pat-ent No. 677,173, dated June 25, 1901.

Application tiled June 29,1900. Serial No. 22,101. (No model.)

To all whom, it may concern.:

Be it known that we, CARL LEOPOLD BRAM- MERTZ, residing at 174 Adalbertsteinweg, and FRANZ PETER FAUSTEN, residing at 254 Ad albertsteinweg, Aachen, Germany, subjects of the King of Prussia, Emperor of Germany, have invented a certain new and nseful Improvement in Stoves or Ovens for Baking, Roasting, dec., of which the following is a 1o specification.

This invention relates to a stove for baking, roasting, dac., in which a better utilization of the hot gases is obtained than heretofore by allowing the said hot gases to envelop r 5 the stove on all sides. In the stoves heretofore known the side containing the door is entirelyneglected,andtherefore the stove cannot be heated from this side. From this there results an uneven baking or roasting of the zo object in the stove or oven. This defect is removed, according,l to 'the present invention, by employing a device which permits the heating of the stove or oven on all sides. The heating can take place by means of a separate furnace or the furnace ofa chamber-stove or the like.

The accompanying drawings show the new stove,which is composed of two boxes or casings-:an outer and an inner.

Figure l is an inside view of the outer box or casing after removal of the upper wall. Fig. 2 shows the same in vertical longitudinal section. Fig. 3 is a vertical longitudinal section of what is termed the f inner casing. Fig. t is a front elevation thereof. Fig. 5 is a sectional elevation showing the invention as used in connection with a stove.

The box or casing is provided with a baseplate a, which has an aperture or inlet for 4o the hot gases. c c' are supporting-bars for the inner casing. Into the front part of the casing, between the side walls d d,there extend upper and lower regulating-dampers e e', which serve for shutting off the upper and lower heating-passages when the door of the stove or oven is opened, and thus prevent escape of the hot gases. The cover-plate h of the casing is provided with gas-outlet apertures z' i', which can be fitted with regulatingvalvesjj. The door of the outer casing in 5o the present instance is made double, the smaller door 'n' serving for closing the inner casing, while the larger door nis for the outer casing. The small door n is connected to the larger door n in such a manner that as large a free space as possible is left between the two and a sufficient surface is presented to the entering hot gases.

The casing 0, which forms the baking or roasting chamber or oven, is closed on all 6o sides, With the exception of the front. It is provided with lateral projections p p', which serve for preventing escape of a portion of the hot gases laterally when the door of the outer casing is opened. On its under side the casing is provided with a guard-plate r, which prevents the hot gases from owing di rectly against the bottom plate of the casing and simultaneously serves' as a distributer for the hot gases.

In Fig. 5 is shown the improved stove or oven combined with an ordinary chamber or kitchen stove. The eduction or smoke pipe t of the chamber-stove s is provided with a valve u, by means of which the hot gases can 7 5V be shut oif, so that they are forced to pass through the aperture o into the baking stove or oven. The hot gases here envelop the innercasing o on all sides and then enter through the outlet-opening t' z" into an extension k, 8o from which they pass through the pipe w into the pipe t of the chamber-stove.

The improved stove or oven can be used not only forA domestic purposes for cooking, roasting, baking, drying, Sac., but also for industrial purposes, such asdrying, lacquering, bronzing, annealing, dac. In the former case the stove or oven may be entirely made of iron, and inthe latter case it maybe made of iron or refractory bricks, and the doors may 9o be protected by insulating material.

The fuel and the heatinggases may tional. y

Having now described our invention, what we claim as new, and desire to secure byLetters Patent, isfbe op- In a stove, an outer easing, an inner easing In Witness whereof We have hereunto set arranged therein and forming an oven with a our hands in presence of two Witnesses.
